Convert 8-bit ASCII to BCD number | 8086 Microprocessor

In this tutorial, we will learn how to convert 8-bit ASCII to BCD number using 8086 Microprocessor? By Akash Kumar Last updated : May 22, 2023

Problem Statement

To convert ASCII to BCD 8-bit number using 8086 Microprocessor.

Algorithm

  1. Load the value from memory into register AL
  2. Then perform and operation on register AL with 0F
  3. Move the result value from register AL to memory
  4. Terminate the program

Program

MOV     AL, [0600]
AND     AL, 0F
MOV     [0601], AL
HLT

Observation

INPUT: 
0600:35

OUTPUT: 
0601:05

Hence we successfully converted 8 bit ASCII number to its equivalent BCD using 8086 Microprocessor.
